推荐答案

我现在可以想到的方法之一是...为此使用Javascript.
您将需要使用setInterval 和UpdatePanel/PageMethod/CallBack.

对于 setInterval ，它在指定的延迟后触发，并在相同的延迟后再次触发，直到被取消.:

您可以在此处选择任何一种AJAX方法.基于页面中的setInterval函数，您可以一次又一次重新绑定数据列表.
例如，如果您选择更新面板":在面板内部有一个虚拟按钮以及数据列表.在setInterval javascript函数中单击按钮.更新面板得到部分刷新

One of the ways i can think of right now is... using Javascript for it.
You would need to use setInterval and UpdatePanel/PageMethod/CallBack.

For setInterval that fires after the specified delay, and keeps firing again after the same delay, until it is cancelled.:
http://www.howtocreate.co.uk/tutorials/javascript/timers[^]

you can pick any one of the AJAX methods here. Based on the setInterval function in your page, you can re-bind datalist again and again.
For example if you choose Update Panel: Have a dummy button inside panel along with datalist. Fire the button click in the setInterval javascript function. Update panel get partial refresh

使用定时器控件 [ ^ ].
在Timer_Tick事件上，编写代码以从数据库获取新数据并将其绑定.

希望这会有所帮助！

Use a Timer Control[^].
On the Timer_Tick event, write the code to get the fresh data from database and bind it.

Hope this helps!

函数Update()
{
setTimeout("__ doPostBack(" CountrolID，"'')，" TimeDelayInMilliseconds);
}
& lt;/script& gt;

function Update()
{
setTimeout("__doPostBack(''CountrolID'','''')","TimeDelayInMilliseconds");
}
</script>
